India’s territorial limit extends towards the sea up to

India's territorial limit, also known as its territorial waters, extends into the sea to a distance of 12 nautical miles (approximately 22.2 km) measured from the appropriate baseline [4]. This limit is established under the Territorial Waters, Continental Shelf, Exclusive Economic Zone and Other Maritime Zones Act, 1976, which asserts India's sovereignty over these waters, the underlying seabed, subsoil, and the airspace above them [5]. This 12-nautical-mile limit aligns with the international standards set by the United Nations Convention on the Law of the Sea (UNCLOS), which allows every coastal state to establish a territorial sea up to this breadth [6]. Beyond this zone, India also maintains a contiguous zone of 24 nautical miles and an Exclusive Economic Zone (EEZ) extending up to 200 nautical miles for resource exploitation [1].
